color: fix --color=always when output is piped

Also restructures the mode determination as discussed on IRC.
I tried to simplify the code too, while keeping the original
semantics except for the case of --color=always.

  $ hg init t
  $ cd t
  $ echo a > a
  $ hg add a
  $ hg commit -m test
  $ rm .hg/requires
  $ hg tip
  abort: index 00changelog.i unknown format 2!

  $ echo indoor-pool > .hg/requires
  $ hg tip
  abort: unknown repository format: requires feature 'indoor-pool' (upgrade Mercurial)!
